SEAL-LOCK.

SPECIFICATION forming part of Iletters Patent No. 369.884, dated September 131, 1887.

Application filed m 26', 1887.

T aZZ whom it may concern:

Be it known that we, FRANK WILLIAM RICHEY and SUMNER M. RoBBINs, of Raton, in the county of Colfax and Territory of New Mexico, have invented a new and Improved Seal-Lock, of which the following is a full, clear, and exact description.

Thisinvention relates to seal-locksforfreightcar doors, the objectof the invention being to provideasimple, cheap, and durable seal-lock and one which may be operated without the use of pinchers or pliers; and to this end the invention consists of a lock and bolt adapted to receive a sealing-strip, as will be hereinafter more fully described, and specifically pointed out in the claims. I

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a side view of a car-door and a portion of a car-body, representing the same as being provided with our improved form of seal-lock. Fig. 2 is a crosssectional view taken on line 00 a: of Fig. 1. Fig. 3 is a sec tional plan view taken onlineyyofFig. 1. Fig. 4 is a view of the sealing-strip prior to its use, and Fig. 5 is a view of the strip as it appears after having been used in the lock.

In the drawings above referred to, represents the car-door, which may be hung in any of the well-known ways. To this door there is connected a hasp, 11, the end of which is apertured, as shown at 12, to receive a staple, 13, that is driven in and secured to the door-post. Beneath this staple I mount a lock case, 14, that is arranged to receive a locking-bolt, 15, and also to receive a sealingstrip, 16, which is inserted through apertures 2,that are formed in the side walls of the lock-case. That end of the bolt whichenters the case 14 is provided with a spring-tongue, 17, the extreme end of which is bent outward, while the extreme end of the bolt proper is cut away, as 5 shown at 3. Just beyond this cut-away por' tion 3 there is formed a shoulder, 4, so that there is a space between the tongue 17 and the bolt, and in this space, as will he hereinafter explained, the sealingstrip 16 rests. The

spring-tongue 17 is formed with an aperture,

Serial No. 239,423. (Model.)

5, beneath which there is a registering aperture, 6, formed in the bolt 15.

A plunger, 18, that is formedwith a punchpoint, 19, is mounted in a housing, 20, which extends outward from the lock-case 14, the plunger being normally held in the position in which it is shown in Fig. 3 by the action of a spring, 21, which is coiled about the plungerstem and abuts against a flange, 22, that is I formed between the punch-point 19 and the stern of the plunger. The seals which are shown in Fig. 4 consist of strips of metal on which there are formed projections 7.

In practice. when it is desired to seal a lock, the hasp 11 is brought into engagement with the staple 13, and the bolt 15 is passed through the staple and into the lock-case 14, one of the sealing -strips having been previously inserted within the apertures 2 of the lock-case, the sealing-strip being soadjusted 7c that its bosses or projections 7 will be upon either side of the bolt cavity. Then. asthe bolt is forced inward, the plunger at this time being drawn back against the tension of the spring, the sealingstrip will be borne upon by either the outturned edge of the springtongue 17 or by the cut-away face 8 of the bolt, and as the bolt is forced home the sealingstrip will enter the space above the shoulder 4. After the parts have been adjusted as de- 8 scribed, the point of the plunger is permit ed to enter the slot in the spring-tongue 17. The lock is now sealed, for the sealing-strip cannot be drawn out of the lock-case,owing to the formation of its projections 7, said projections be ing of sufficient size to prevent the drawing of the strip between the bolt end and the tongue formed thereby, nor can the bolt be withdrawn, as its shoulder 4 will strike against the sealing-strip; but when the car has reached its c destination and it is desired to open the door a slight tap upon the extending end of the plunger will force the point 19 inward and the sealing strip will be severed, as is represented in Fig. 5, after which the ends of the severed 5 strip may be removed from the lock-case and the bolt Withdrawn.

Now, although we have illustrated this seal- ]ock as arranged in connection with a hasp fastener, it will of, course he understood that Ice any other form of fastening employing a bolt might be used in connection with a lock.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent- 1. The combination, with an apertured bolt provided with an apertured springtongue and formed with a shoulder near its forward end, of a lock'case adapted to receive the bolt and formed with transverse openi ngs, and aplunger carried by the lock-case and adapted to enter the apertures of the spring tongue and bolt, substantially as described.

2. The combination, with abolt formed with with an outturned end, a bolt or look case,l4,

formed with transverse apertures, a sealingstrip, 16, formed with projections 7, and a means, substantially as described, for break- 20 ing the strip, as and for the purpose stated.

3. The combination, with a bolt formed with a cut-away end, 3, a shoulder, 4, and an aperture, 6, of a springtongue, 17, formed with an aperture, 5, and an outturned end, a bolt or 25 lock case formed with apertures 2, a plunger, 18, a spring, 21, arranged in connection with the plunger, and a sealing-strip, 16, formed with projections 7, substantially as described.
